Phone Grope

Grabbing at pockets, patting yourself down to make sure you have your cellphone and don't need to turn around and go back home for it. This behaviour tends to be heightened in people who also have a habit of going back to check the locks on the doors several times before leaving home.

Dude, stop that.

What?

Quit the phone grope. You're always grabbing at your pockets as soon as we're on the road. Didn't you remember your cell?
